Definition - What does Convict mean?
Convict means to declare a person guilty at the conclusion of a trial. If a jury has given a guilty verdict for the defendant after all of the proceedings are over, then the defendant is said to be convicted. A convicted person can be sentenced to jail or face other legal punishments. This is why people in prison are often referred to as convicts.
Justipedia explains Convict
The word convict essentially means to find guilty. Defendants in criminal trials try to avoid being convicted. The whole purpose of criminal trials is to find out whether or not the jury will convict the defendant. The defense attempts to prove that the accused person is not guilty, and the prosecution attempts to prove that they are guilty. Ultimately the jury must decide, and if they find the defendant guilty, then they can be sent to jail
